摘要
研究了不确定非线性结构扰动的广义系统的鲁棒控制和保性能控制问题.目的是分别设计系统的鲁棒控制器和保性能控制器。应用线性矩阵不等式方法,分别给出了系统的鲁棒控制器和保性能控制器存在的充分条件;并在这些条件可解时,分别给出了鲁棒控制器和保性能控制器的表达式。最后用例子说明了所给方法的应用.
Robust control and guaranteed cost control problems for uncertain nonlinear structured perturbation systems are discussed. The aim is to design a robust controller and a guaranteed cost controller. By means of the linear matrix inequality approach （LMI）, sufficient conditions for existence of robust controller and guaranteed cost controller are presented. When these LMIs are feasible, explicit expressions of robust controller and guaranteed cost controllers are obtained respectively. Finally, a numerical example is provided to demonstrate the application of the proposed method.
